`set' does not affect the environment at all, these are just local Tcl
variables.
If you need special variables in the environment for building, specify
configure.env (and build.env) in the Portfile. But also note there are
predefined options to set CFLAGS, LDFLAGS and others, namely
configure.cflags, configure.ldflags, etc. They should be preferred over
manipulating configure.env.
They are explained in the guide:
